We could have a Sanctified Drax and Sanctified Pickaxe Axe. Additionally, the Excalibur might still be able to be crafted with Sanctified Bars but maybe a new, similar sword could be introduced as an analog? I'm also not sure what you would call a Sanctified spear weapon and a Sanctified whip. There would be also have to be a Sanctified Jousting Lance.
Additionally, the player should be able to decide between having the Sanctity and having the Hallow in a similar fashion to how they can choose between the Corruption and the Crimson. They would also receive a Sanctity-themed (the Pwnhammer is technically a Hallowed hammer so there should be a different one) hammer upon killing the Wall of Flesh. Although, again, I'm not sure what you'd call it.
As well as this, in the drunk world seed, both the Sanctity and the Hallow would generate after defeating the Wall of Flesh.
